Yield increase of VLSI after redundancy-repairing
J. Hirase · 2002
A topic of great concern in VLSI manufacture is yield. One way to improve practical yield is to design redundant memory or logic circuits and switch over to this redundant circuit if fault occurs in the principle memory or main logic circuit. This paper reports the repairing ratio of no good devices on the main circuit and how large of a redundancy-repairing circuit would be economically feasible.
